I would also like to see manageable amounts of update traffic. In the old days I had De Lorme street maps of the whole US. It was sold on a CD-ROM so the whole dataset was at most 700MB. It didn't have updates. I also have paper maps (Thomas Guide) of my local region in my car, from the 1990s, and they're still perfectly good in most places. Roads don't move around THAT often. But I have Organic Maps (predecessor of Comaps, maybe I should switch) for just some parts of California and that by itself is more than 1GB of updates EVERY MONTH.

Really seriously, if I go to someplace out of my area I might download that place's map of 500MB or whatever, but then I probably want to just leave it on my phone in case I go there again, no updates needed. I'd like an install for the entire US to be no bigger than say 100GB (my phone "only" has 256GB of storage), and maybe I want monthly updates for my local region of 200MB/month, then perhaps annual updates for everything else unless marked as being of special interest. Plus manual update on demand for wherever if I think I might travel there.
